BY will/ 5 B. H/NPs ATTORNEYS q Patented Nov. 5, 1940 UNiT stars 1Claim.

This invention relates to a portable folding seat and more particularlyto a seat for use at a stadium, a gymnasium or the like, where the seatsare constructed out of concrete, iron or wood without back supportingmeans.

The seats in the stadium are usually exposed to the weather, with theresult, that in cold, wet weather they are very undesirable to sit on.To overcome this very undesirable feature, the spectator usually carrieshis or her own cushion, blanket etc. to sit on during the game.

It is an object of the invention to provide a portable folding seat thatwill overcome these undesirable features, that is serviceable, durable,and may be cheaply manufactured.

Other features of the invention consists in the details of constructionand combination of parts hereinafter more fully set forth.

The invention and its aims and objects will be clearly understood fromthe following description taken in connection with the accompanyingdrawing of one embodiment of the invention herein given for illustrativepurposes, the true scope of the invention being more fully pointed outin the appended claim.

Referring to the accompanying explanatory drawing:

Figure 1 is a side View of the seatin open position.

Figure 2 is a side view of one of ing means detached from the seat.

Figure 3 is a front view of the clamping means shown in Figure 2.

Figure 4 is a plan view of the clamp shown in Figures 2 and 3.

Figure 5 is a front view of the clamping means, showing the seat clampedto a supporting base or seat. The back of the seat is shown fragmentary, also the support.

Similar reference numerals are applied to corresponding parts throughoutthe several views.

The chair or portable seat may be manufactured out of any suitable,light, strong materials and includes a bottom l0 and a back II pivotallyconnected to the bottom or seat portion by means of brackets l2 and I3which are secured to the seat by means of pivots l4 and a washer theclamp- I5. Pivoted link members l6, 11, I8 andl9 arranged in pairs areconnected to the side edges of the bottom 20 and 2| and the back as at22 and 23, to limit the swinging of the back beyond a predeterminedangle.

The clampingmeans 24 and 25 are secured to the under side of the seatand toward the front thereof as shown in Figure 1 at 2B.

The clamps are identical in their structure save that one is a right andthe other is a left, a description of one will, it is believed, suffice.and reference is now made for that purpose to Figures 1, 2, 3, and 4 and5. The clamp comprises a bearing plate 27 of U configuration having itsends bent at an angle of which are provided with holes for the receptionof screws 10 or other suitable fasting means by means of which thebearing plate or bracket may be attached to the under side of the frontedge of the seat portion. The bearing plate or bracket is provided withaligned bores 28 and 29. The bracket is so formed that it providespartial housing for the helical spring 30. The clamp member is of a Ushaped configuration as shown in Figure 4. One leg 35 of the U ismounted in the aligned bores in the bearing plate as shown best inFigure 2. Around this leg there is provided the helical spring 33',adapted to normally force the leg 32 to the right as shown in Figure 5when the clamp is opened to mount same, and to maintain the clamp in theposition shown in 25 Figures 1 and 3 when the seat is detached from asupport. The clamp just described is a left, it is to be understood thatthe right normally forces the leg to the left as shown in Figure 5 at33. i A suitable stop pin 34 is arranged in the 30 leg in the supportingplate. One end of the helical spring is connected to the pin as shown at35, while the other end engages the under side .of the seat as at 36.The legs of the U shaped member may be of equal length as shown inFigure 4. Intermediate the legs of the U there is provided a- V shapedbend 31, see Figures 3, 4 and 5. It will be noted in Figures 1, 2 and 3that a portion of the bend 38 extends down 40 beyond the bottom 39 ofthe bearing plate, to provide a means to keep the seat from slippingback on the support when the clamps can not be used. The V shaped bendalso provides a means to prevent slipping on the thumbs or fingers inmounting the seat on a support such as shown in Figure 5. Intermediatethe length of the bearing plate there is provided a protuberance 40adapted to prevent slipping of the seat on the support, see Figures 1,2, and 3 at 40 and 4|. The seat portion is also provided with resilientsupports 42 and 43 made of rubber or the like.

It is believed that the operation of the device, as a whole, will beclear, in view of the foregoing description which has been given inconnection with the construction of the same.

I am aware that my invention may be embodied in other specific formswithout departing from the spirit or essential attributes thereof; and Itherefore desire the present embodiment to be considered in all respectsillustrative and not restrictive, reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.

I claim:

A portable folding seat consisting of a seat portion, a back portionpivotally. attached thereto, pivoted link supports pivotally attached tothe aforesaid portions and provided for the purpose of holding the backportion in correct relation with the seat while in use, fixed U shapedbrackets having aligned bores therein and having their ends bent at anangle of 90 attached under and adjacent the front edge of the seatportion, clamping members of U shaped configuration, each having. a legmounted in the aligned bores in each of the U shaped brackets, a stoppin in each of the legs mounted in the brackets, a helical springsurrounding the leg and having one end attached to the stop pin, theother end of the helical spring engaging a portion of the under side ofthe seat portion, fixed India rubber feet attached to the under side ofthe seat portion and rearwardly of the fixed U shaped brackets, thefixed brackets and the India rubber feet acting jointly to provide thefeet.
